To (JIM/710m it may concern:

Be it known hat l. (inns'rornitn C. Bot- KIX. a ritizen of the lnitt-tl States, residing at Norfolk. in the eounl of Norfolk atnl State of Virginia. have invented new aml useful Improvements: in llollel' 'intlow- Screens, of whieh the following is a spewifieation.

The present invention relates to iltll)l'tt.tments in wimlow set-ems aml p:u-tieularl v of the t vpe wherein the sen-en is :nlaptetl to he woutul null unwouml with respet-t to a rolleix 2i!l(l it has-for its ohjeet primarih to provide a t-teen of thi (lass whh'h is adapter] to he loeatetl in sin-h a position within the wintlow. frame as not to interfere with the raising aml lowering of the inner or lower wimlow sash. although it will Screen at all times the opening hetween the uppe aml lowensashes a well as the win- (low opening pr vitletl h the. raising; of the lower sasln the loeatinn of the srreezt lit-int! sueh that the liliml tixtures tlt) not interfere with the operation of the scre n.

Another ohjert of the i nention is to provide a srreen of this elass whivh may he readily mounted in the wimlow frame or easing. the parts of the (levi -e eoiiperating in such a manner as to lock or retain the device in position, thus avoiding the necessity of screwing, nailing or otherwise fastening the screen to the window frame ittltl at the same time enabling unskilled persons to readily place the screen in position for use,

it being also possible to readily remove the screen when desired.

Further objects of the invention are to provide guiilez for the marginal edges of the screen .whieh are of surh a eonstruetion as to prevent the entraure of flies or insects at such edges, to provide a slitle to which the free etlgge of the ereen is attarhetl in such a manner as to insure the proper tension .upon the marginal wines of tilt :a-reen so as to retain it in close relation with the guides, said slitle slitlahly engaging the guides at the sitlo of the winrlmv opening. atitl to a'so provide tleviees; whirl: :na5 he atljus'tetl izttu a position to engage th rreen antl prevent. its being tll'tHYll iuwarilly hy wiutl. stir-h ileviees bent; aatomaiiraily returneil to ino erative position hy the rollinp or liftin; of the. s reen.

- In the present emhotliuu-nt of the inven tion, I haveshown eonventionally :1 rommon form of wintlow easing i haxiug' grooves 52 antl 1-1 within \\'lll('ll the lower awl upper sushi-Is 4 aml 3 slith- \tl'llt'I!ll th se gro ves lMlHg eparated by a heart (3. The sereen ttt'ttll'tllhg to the pr sent invention is mounted beneathvthe upper sash' and outside of the plane of movement of the lower sash and, in the present instance, the device comprises a roller 7 which is preferably of a type embodying a spring which normally tends to wind the screen cloth 8 which is wound thereon, this roller having pintles 9 which are journaled in suitable bearings 10 formed at the opposite ends of a casing 11, this casing being preferably composed of sheet metal and is of a form to lit snugly beneath the bottom rail of the upper sash and it incloses the roller at the top and the inner and outer sides, the bottom of the casing being left open to permit the winding and unwinding movementsof-the screen cloth. In order to seal the space between the casing and the screen cloth, the inner free edge of the casing is preferably provided with a curved edge 12 which is adapted to bear against or lie in close relation to the screen cloth at a point adjacent to the roller.

According to the present invention, the roller supporting casing is locked within the window frame by a pair of vertical strips 13 and 1-1 which preferably fit into the groove 3 for the upper sash. For this purpose, the casing is provided at its ends wi 1 blocks 15 which are shaped to fit into the groove 3 beneath the upper sash, and the lower edges of these blocks are beveled to form the inclined or wedge surfaces 16. The upper ends of the vertical strips 13 and 14 are also beveled at an angle to correspond nnd coiiperatc with the beveled or inclined surfaces of the blocks upon the ends of thetroller casing. By first inserting the easing into the groove 3 beneath the top sash and then inserting the vertical strips into the grooves by a tilting movement, a wedge engagement is produced between the roller casing an d 'the vertical strips and the roller casing will 'be forced upwardly into close relation with the bottom rail of the upper sash and will be supported in such position, the lower ends of the strips 1 and 14 resting upon the window sill.

'l'he wedge engagement referred to is pro duced because of the downward and inward bcveling of the ends of the roller casing and the upper ends of the guiding strips, the strips being tilted into the grooves of the window frame by a turning movement about the beveled surfaces as approximate centers, and as the. lower ends of the Strips rest upon the window sill while they are being so tilted into position, it is obvious that such strips would be forced upwardly. and owing to the complcmcntal beveled surfzv-es, it is obvious that the fox-ding up.

wardly of the strips will causethc roller casing to be firmly bound between the upper ends of the strips, and the reaction will cause the upper ends of the strips to be forced apart so as to obtain a firm seating in the bottoms of the sash-guiding grooves.

In order to insure a close fitting of the vertical strips 13 and 14 within the, grooves 3 in which the upper sash is adapted to move, and furthermore to enable these strips to accommodate themselves to window frames wherein such grooves are of difi'erent widths, each of the strips is provided with one or more screws 17, a pair of these screws being shown in the present instance which extend into the outer edge of the strip. Obviously, by adjusting the depth ofjhe screws in each strip, the strip togcther with the heads of the screws will form a close tit within the groove. The edge of each strip beneath each screw head is preferably recessed as at 18 in order to accommodate the screw heads when the strips are applied to window frames having grooves of a minimum width. These vertical strips 13 and ll in the present instance serve also as supports for lateral guides for the screen cloth. these guides in the present instance consisting of plates 19 and 20 which are secured to the inner edges of the strips and, in order to insure a close tit between these guides and the lateral margins of the screen cloth. the plates forming these guides -are bowed outwardly toward their centers as shown in Fig.

according to.tlie,prescnt invention is provided with a slide to which it is attached in a novel manner whereby tension upon the margins ofjhc screen cloth will be maintained so as to keepthese marginal edges in close relation to the lateral guides. This slide in the presentinstance consists of a cross-rail 21 which extends between and is -ull'l'ul1gctl at the inner sides of the lateral, guides it) and 20 and, in the present instance, has its outer side recessed toward its ends to accommodate the lateral guides. The lower or free edge of the screen cloth is attached to a binding strip 22 which is preferably formed of sheet metal, and screws or other suitable fastening devices 23 connectthe binding strip to the rail 21 at points in immediate proximity to its ends, the central or intermediate portion of the binding strip being unattached to the rail 21 whereby this middle portion of the binding strip may sprin upwardly a sufiicient extent to maintain t to greatesttension upon the marginal edges of the screen cloth. The construction just described also facilitates a renecessary.

In order to revent the screen from blowing inwardlyfl also provide a pair of reinforcing deviccs 24 one of which is pivoted to the inner side of each guide, the pivot 25 of each reinforcing device being preferablylocated at a point outwardly beyond the ad- The lower OhflLQ edge of the screen cloth newal of the screen cloth when desirable or these devices and automatically return them to vertical or inoperative positions. To insure the proper engagement of the ends of the rail 21 with the reinforcing devices, the inner edges of these devices in the present instance are turned laterally to form relatively wide. flanges 26. Any suitable means may be provided for retaining the screen in lowered position. a catch 37 being shown in the present instance which is driven into or otherwise fastened to the window sill and is sutiiciently compact to avoid interfering with the closing of the lower sash.
